WILLIAM I. BETENDORF, OF DAVENPORT, IOIYA.

TANK-CAR.

SPECIFICATION forming part of Letters Patent No' 788,016, dated April25, 1905.

Application filed March 30, 1904. Serial No. 200,830.

lie it known that I, WILLIAM P. Bn'r'rnxnoun, a citizen of the UnitedStates, and a resident of Davenport, in the county of Scott and State ofIowa, have invented certain new and useful Improvements in 'Iank-Cars,of which the following is a full, clear, and exact description.

Tank-cars now in use are so constructed that the draft-rigging and theline of draft therethrough are below the rank. Considering the side washof the oil or other liquid contents of the tank while the car is inmotion, the danger of the car turning over because of the greatcentrifugal force when rounding curves or jumping the tracks is a sourceof anxiety to railroad men.

The object of my invention is to so construct the car as to lower thecenter of gravity of the tank, and thus minimize this danger. This Iaccomplish by the means hereinafter fully described, and as particularlypointed out in the claims.

In the drawings. Figure 1 is a longitudinal central section of atank-car embodying my invention. Fig. 2 is a longitudinal centralsection of one of the said tank-cars, drawn to a larger scale and takenon dotted line 2 2, Fig. 3, looking in the direction indicated by thearrows. Fig. 3 isan end view of the lower portion of one end of thetank, drawn to a still larger scale. Fig. t is a transverse sectiontaken on dotted line *1 ".l:, Fig. 2, looking in the direction indicatedby the arrows, buton a slightly larger scale. Fig. 5 is a plan view ofthe under side of the tank, illustrating the manner in which it isprepared to receive my improvements. Fig. 6 is an end view of the same.Fig. 7 is a transverse section of the tank, illustrating a modifiedconstruction of the butfer-colunm.

Referring to the drawings, A represents a suitable tank which isprovided with a longitu linally-elongated rectangular opening a in eachend, which extends from an opening of about the same width in the headsthereof back therefrom past the transverse plane of the truclvpivot.Placed in these openings (1 I) is an inverted channel shaped draftrigging frame B, which is preferably cast in one piece of metal and hasits lower longitudinal edges provided with lateral flanges e c, that lapagainst the under side of the shell of the tank adjacent to said openingand are riveted or otherwise securely fastened thereto. The forward endsof the rigging-frame B, which exl tend through opening in the tank, arealso provided with lateral flanges that form a shield C, which isriveted or otherwise suitably secured to the outer surface of the headof the tank and greatly strengthens and reinforces the same. The end .rof the channeled portion of the rigging-frame opposite the shield Uterminates just before it reaches the center plate and is closed, andbetween this closed end .11 and the head of the tank said frame isprovided on its vertical sides with in ardly-projecting vertical stops1/4, that are engaged by f at the entrance of the channel of theriggingframe and under the yoke thereof by a suitable cross-frame E,whose downturned side edges are bolted or riveted to the sides of thechannel of frame B, which latter has its lower edges dropped slightly atthis point.

The rigging-frame B extends back from its closed end a' in a planecorresponding to that of the shell of the tank, and this extensionpasses over the truck-bolster and has the body center-plate (/I suitablysecured to the under side thereof. The rear edge of this extension hascast in one piece therewith and arising therefrom a lmliing-hcad F,consisting, preferably, of a solid block of metal of about the sameheight and width as the channeled portion of the rigging-frame, to whichit is connected by a centrally-located longitudinallydisposed verticalweb 7/. The vertical side of this head farthest from the channeledportion of frame B is provided with a longitudinal central opening, andsecured in the opening of the head F of the draft-rigging frame at eachend of the tank is a tubular bultingcolmnn. The ollice of thisbutting-column is to take up the strain of the pull of the draw-bar andthe shock of the humping of the cars and to relieve the shell of thetank therefrom and in addition to serve as a steam-chamber to keep theliquid contents of the tank warm, particularly in cold weather. Steam isintroduced into column G through vertical inletports H, made in saidheads F, to the lower ends of which suitable steam-pipes J areconnected, substantially as shown. The bufiingcolumn is preferably ofsuch dimensions that the necessity for the presence of other steampipesin the tank is dispensed with, and it forms a continuous connectionbetween the draftrigging frame and practically takes the place of centersills. If desired, the buffing-column could between the heads F beprovided with a series of looped pipe connections I, whose ends, spiderfashion, would radiate therefrom and which between their ends would runsubstantially parallel with said column. Such an arrangement of steampipes might be deemed desirable in cold climates; but I do not desire tobe confined to their use nor to the exact location of the buffing-columnas shown.

In the construction of my improved car the connections between thedraft-rigging frame B and the tank A are made as tight as possible toprevent the leakage of the contents of the car. Such leakage may befurther guarded against by partitioning off the lower portion of theends of the tank in which the draft-rigging frames are secured, so thatan empty chamber surrounds the same. This I accomplish by a sheet-metalcover K, that arches over the rigging-frame B, as shown in Figs. 2 and 4of the drawings, and has its end farthest from the head of the tank bentvertically down and clamped against the adjacent vertical surface of thebuffing-head F by the circumferential flange Z1, projecting from thebuffing-column near their ends. The edges of this cover K bearingagainst the inner surface of the head of the tank the longitudinal edgesof said cover. and the transverse edges of the end of the samecontiguous to the buffing-head are all flanged and riveted or otherwisesuitably secured to the shell of said tank. The construction of thedraft-rigging frame may be modified to suit the type or style ofdraft-rigging set forth in the specifications of the purchaser and maybe so designed and made as to allow the horizontal plane of said frameto be relatively higher or lower in said tank than as shown. All suchchanges I desire to be considered as contemplated within the spirit ofmy invention, the object of which, briefly stated, is to lower thecenter of gravity of the tank, and by thus reducing the height of thetriangle, of which the center of gravity is the apex and the ball of therails of the track the lower angles, broaden the base upon which the caris supported and give greater stability to the same when in motion.
